The mind feels calmer, clearer, and sharper. Cognitive awareness is improved.
My sleep patterns have changed. I used to sleep poorly, waking many times during the night and often finding it difficult to go back to sleep. Now I am sleepy at bedtime, which is no change, and need to pee usually twice instead of four, and return to sleep almost immediately. I wake up between 4:30 and 5:00, which is way too early, and get up about 5:30. I need less sleep.
